I had a set of [url="http://www.newegg.com/Product/Product.aspx?Item=N82E16820226095&Tpk=996770"]996770[/url] that produced 1 error per pass of memtest 86+, so I bought a set of [url="http://www.newegg.com/Product/Product.aspx?Item=N82E16820226099"]996776[/url] to replace it. For a while, I couldn't get it to boot, and only by using the XMS profile could I get it working (manually inputting the timings and voltage didn't help), and it was stable in Windows. However, during Memtest 86+, it would get through one pass, partially through another, and stop altogether. The timer stopped with it. Is the RAM bad? Is there something else I should look at? The other set, 996770, would run as long as I left it and would reliably produce 1 error per pass. This time, no errors came back, but Memtest stopped.

Memtest is being run from a 4GB PNY Flash drive that has no obvious issues.

Common issues:Defective memory, or memory not capable of running the advertised spec (same as defective to me)Defective memory controller (on motherboard) or memory controller no capable of running the advertised spec (same as defective to me)Incorrect memory timingsIncorrect memory voltage

Rare issues:Power supply out of regulation (causes random issues)Bad CPU (specifically will fail tests that include the L2 Cache but not others)

Extremely Rare:Other hardware causing issues with the motherboard at a low levelbug in memtest+ 4.2
